Virtual Router Priority Tracking Configuration - Lenovo RackSwitch G8264 Command Reference Manual

Virtual Router Priority Tracking Configuration

606
G8264 Command Reference for ENOS 8.4
These commands are used for modifying the priority system used when electing
the master router from a pool of virtual routers. Various tracking criteria can be
used to bias the election results. Each time one of the tracking criteria is met, the
priority level for the virtual router is increased by an amount defined through the
VRRP Tracking commands.
Criteria are tracked dynamically, continuously updating virtual router priority
levels when enabled. If the virtual router preemption option is enabled, this virtual
router can assume master routing authority when its priority level rises above that
of the current master.
Some tracking criteria apply to standard virtual routers, otherwise called "virtual
interface routers." A virtual server router is defined as any virtual router whose IP
address is the same as any configured virtual server IP address.

VRRP Priority Tracking Configuration Options
Command Syntax and Usage
[no] virtual­router <1‐128> track interfaces
When enabled, the priority for this virtual router will be increased for each
other IP interface active on this switch. An IP interface is considered active
when there is at least one active port on the same VLAN. This helps elect the
virtual routers with the most available routes as the master.
This command is disabled by default.
Command mode: Router VRRP
[no] virtual­router <1‐128> track next­hops
When enabled, the priority for this virtual router will be increased for all active
next hops. A next‐hop is considered active if it is configured.
This command is disabled by default.
Command mode: Router VRRP
[no] virtual­router <1‐128> track ports
When enabled, the priority for this virtual router will be increased for each
active port on the same VLAN. A port is considered "active" if it has a link and
is forwarding traffic. This helps elect the virtual routers with the most
available ports as the master.
This command is disabled by default.
